Entropy, area, and the choice of regulator during gravitational collapse

Jana N. Guenther, Christian Hoelbling, Sophie Mutzel +1

We present a real time formalism to numerically describe the gravitational collapse of a scalar quantum field in the spherically symmetric case. We employ a Pauli-Villars regulator…

Electric charge fluctuations from lattice QCD in the continuum limit

Szabolcs Borsányi, Zoltán Fodor, Jana N. Guenther +5

Electric charge fluctuations allow comparisons between theory and experiment, but are elusive on the lattice due to severe cutoff effects. We use a 4HEX action to obtain $χ…

Finite density lattice QCD without extrapolation: Bulk thermodynamics with physical quark masses from the canonical ensemble

Alexander Adam, Szabolcs Borsányi, Zoltán Fodor +5

Quantum Chromodynamics (QCD) at finite density is most often formulated on the lattice as a grand canonical ensemble. Since lattice QCD has a complex action problem at finite baryo…

Finite density lattice QCD without extrapolations

Alexander Adam, Szabolcs Borsányi, Zoltán Fodor +5

Finite density lattice QCD usually relies on extrapolations in baryon chemical potential (), be it Taylor expansion, T' expansion (\cite{Borsanyi:2021sxv}) or analytical conti…
